SPRINKLER Filed Feb. '7, 1934 -T TDENEYS.

Patented Oct. 8, 1935 UNITED STATES PATENT OFFICE SPRINKLER Jean Ghislain, Downey, Calif. Application February 7, 1934, Serial No. 710,075

11 Claims.

My invention relates to a rotary type of water sprinkler for lawn watering, or the like.

An object and feature of my invention is the employment of a water jet discharged from a rotary sprinkler head impinging on a rotary interceptor and water spreader. This interceptor is in the `form of a disc and by the impulse of the water jet, is caused to rotate at a relatively high speed. This water spreader is preferably provided with ribs which may extend somewhat radially but preferably in a curve in the form of vanes or vblades for Vdriving the spreader and these vanes or blades cause the water to be thrown outwardly by centrifugal action.

Another feature of my invention comprises providing the spreader with a rim more or less conning the water at the ends of the vanes and this rim is provided with a plurality of openings or notches of diierent sizes to allow a relatively free and more restricted discharge of water radially at the rim, thus giving a variable spread to the circular spray developed by the spreader.

Another detailed feature of my invention relatesto the variable adjustability of the spreader relative to the rotor head having the discharge jet.

A further feature of my invention is varying the speed of the rotor head and the discharge jet or nozzle by changing the inclination of the rotary disc spreader. This causes a variable reaction of the water spray in the air and thus may be used to vary the speed of rotation of the rotary head andthe sprayer as a whole.

My invention is illustrated in connection with the accompanying drawing in which:

Fig. 1 is an elevation.

Fig. 2 is a detailed vertical section on the line `2'2 of Fig. 1 through the rotary head. Fig. 3 is a detailed. vertical section on the line 3 3 of Fig. l in the direction of the arrows through the sprayer.

Fig. 4 is a detailed section on the line 4-4 of Fig. 3 in the direction of the arrows showing the sprayer disc.

Fig. 5 is a detailed section on the line 5-5 of Fig. 1 in the direction of the arrows showing the adjustable mounting of the sprayer disc on the rotary nozzle structure.

In my invention, I employ a suitable stand II having an inlet I2 for the supply water. This inlet connects to a vertical stand pipe I3 which has a coupling I4 connected thereto. Threaded in this coupling there is a nipple I5 having a wrench head I 6. The rotary head I'I is illustrated as being constructed in the form of a T I8 having internal threads I9 on an integral ring 20.V Arotary sleeve 2I is rotatably mounted inside of the nipple and the head I6, and engages the threads I9. This sleeve has an outwardly eX- tending shoulder 22 at the lower end engaging 5 the lower end of the nipple I 5, and being located in the coupling I4. This sleeve has a flared bore 23 at the bottom and a cylindrical bore 24 thereabove and discharges into the rotary head I 'I. Connected to the T I8 of the rotary head there is 1o a nozzle pipe 25 having a slightly upwardly curved discharge nozzle 26. The counter-weight arm 2'I with adjustable counter-weight 27 is used to balance the pipe 25 and the rotary sprayer mounted on the nozzle pipe. This mounting comprises a l5 collar 28 secured by a set screw 29 to the nozzle pipe, a threaded stud 30 extends laterally from this collar and has a wing nut 3l threaded thereon. This is used to jam or clamp the hub end 32 of an arm 33 and thus determine the angularity of 20 this arm in reference to the nozzle pipe 25.

The arm 33 has a socket 34 at its outer end with a set screw 35 which set screw engages the lower contracted end 36 of a spindle 31. This spindle has a contracted cylindrical end 38 at the 25 top withya bushing 39 thereon, and a nut 49.

f Rotatably mounted on the bushing is the rotary spreader 4I. This is in the form of a disc 42 having a series of arcuate vanesfor blades 43. These may be considered as ribs. They are 30` slightly spaced on their inner ends by a space 44 from the hub 45 of the disc and there is also a space 46 between the ends of the vanes and a downwardly turned rim 41 on the disc. This rim is provdedwith a few notches 48 which notches 35 vary in size. (Note Fig. 1.)

Tn the operation of my invention, obviously by having the collar 23 adjustable longitudinally and in a rotary manner in relation to the pipe 25 and discharge nozzle 25, the spreader disc 4l ymay be 40 altered longitudinally of the nozzle 23 and also to one side or the other of this, or above the nozzle so long as the water impinges on the disc. The arm 33 may also be adjusted on the threaded stud'3l, thus regulating the angle on which the 45 water jet nozzle 23 strikes the under side ofthe disc. The impingement of the water on the curved vanes 43 causes a rapid rotation of the disc. Some of the water is caught by the rim 4l' and is deiiected more or less downwardly, theV rim re- 50 stricting the spread of the circular spray. Water which is ejected through notches 43 is projected at a greater distance and as these notches are graduated in size, the water spread outwardly by centrifugal force through the large notches is 55 thrown to a greater distance than that thrown through the' small notches. Moreover, the manner in which the Water impinges on the disc 4I and the reaction of the water discharged from the disc on the air causes a rotation of the rotary head l1 on the stand pipe i3. Thus, the spreader is carried bodily in a circle while it rotates thereby giving a combined action of two rotary sprayers.

Various changes may be made in the details of construction of my invention without departing from the spirit or scope of the appended claims.

I claim:

1. A sprinkler having a water pipe with a nozzle, an arm adjustably mounted on the pipe, a disc rotatably mounted on the arm to receive the water discharged from the nozzle on one face of the disc, and means reacting to the water jet from the nozzle to rotate the said disc, the said reacting means comprising curved vanes on the under side of the disc, a downturned rim on the same side as the vanes, said rim having a plurality of notches varied in size.
